Second Lieutenant Wang Haiyang said: "Let's make preparations and don't get seasick at night."
Li Zheng asked: "Our physical fitness is so good, isn't it? This is not the first time we have gone to sea."
Wang Haiyang said: "That's not true. Seasickness is something that no matter how old a veteran is, it will happen to all veterans. It takes an adaptation period to go sailing. If you don't get dizzy, you are great. If you get dizzy, there is no shame in it."
Li Zheng was very curious about Wang Haiyang's caution.
I have been in Lute for so many years, and I have been studying in Haite for almost half a year. I have also gone out to sea with the team. Although they were all offshore, I have never experienced seasickness.
As an elite special forces soldier, Li Zheng did not believe that he would get seasick.
seasick?
What the hell!
How can it be!
Not to mention anything else, Lu Te also has anti-vertigo training.
It’s all made through hard work, so you won’t get seasick no matter what you do, right?
But in fact nature quickly taught Li Zheng a lesson.
Seasickness is a very strange thing. It does not mean that you will not get sick if you undergo high-intensity training, just like altitude sickness does not mean that you will not get altitude sickness if you are in good health.
Seasickness is more or less evil. Many veteran seafarers will get seasick. If you don't feel sick today, it doesn't mean you won't feel sick tomorrow. If you don't feel sick now, it doesn't mean you won't feel sick in the future. It's just that if your body is strong enough, you will recover quickly after you faint.
That's all the difference.
At around 8 p.m., the ship entered a tropical storm zone.
Since they are still within the waters of their own country, the special operations team members do not need to go outside the cabin to perform guard duty.
At this time, other navy sailors on the ship were very busy, and the most bored ones were the sniper team.
When the boat started to rock, Fatty Wei was still there blowing water, and continued to brag about his fishing experience.
Occasionally, various messages come on the radio.
Everyone learned through the radio that the wind and waves in the current sea area had reached Level 7, and the captain sent someone over to ask everyone if they could adapt.
After all, they are special forces. Who dares to say that they are not suitable?
They all said there was no problem, nothing wrong, nothing happened at all, it was a big deal!
The officer who came to inquire about the situation came with a smile and walked away with a smile. He was walking on flat ground on the rocking ship, which Li Zheng had to admire.
This is experience.
In special operations, their individual soldiers are not as good as yours, but when it comes to adaptability on the ship, they are really better than you, and you have to admit this.
Li Zheng curiously asked Wang Haiyang whether this kind of wind and waves was considered big during a long voyage.
Wang Haiyang said lightly: "It's just so-so, no big deal!"
As the saying goes, there is no wind without waves. In the wind level comparison table, a force 10 wind can produce waves of about 9 meters, while a force 11 wind can produce huge waves of 11 meters. The maximum wind wave of a typhoon of force 12 is 14 meters, which means that the sea state of a 10-meter wave
The wind is slightly higher than level 10.
Warships are surface ships that operate in all sea areas and in all environments. Therefore, their ability to withstand wind and waves has more stringent requirements than ordinary merchant ships. Wind and waves are a major test for the strength, sinking resistance, and stability of the ship's hull.
Our country divides the wind and wave resistance capabilities of ships into five levels, of which level one can withstand winds of level 12, while level two can withstand winds of level 11.
Except for logistics supply ships, front-line combat ships are usually divided into levels based on displacement, with small frigates ranging from 1000 to 2500 being level 2.
In other words, even small-tonnage ships such as the Type 056 frigate can withstand winds of level 11 and waves of about 9 meters.
Ships above 2,500 tons are the highest level, which means that destroyers and frigates above the 054a frigate have the ability to sail in level 12 typhoons and waves of more than 11 meters.
The displacement of the 052 series destroyers is generally more than 5,000 tons, and the displacement of the 055 large-scale destroyers is more than 10,000 tons. It is natural to cope with wind and waves of more than 10 meters.
If it is an aircraft carrier, the large ship can sail safely in 14 super typhoons and huge waves of more than 15 meters without any problems.
So how do warships ensure that they can sail in strong winds and waves without being blown over or overturned by waves? There are three main reasons:
First of all, the appearance design. The reason why the ship cannot sink is because the buoyancy is greater than the gravity, so the ability to resist wind and waves must be improved. If the ship takes in too much water during navigation, it will cause its own gravity to be too large, and finally the waterline will become deeper, causing capsizing.
There is even a risk of sinking. Currently, mainstream warships adopt a fully enclosed design, and the deck adopts an arched design. There are also multiple water holes designed around the hull, which can minimize the water intrusion in wind and waves.
The second is the pressurized water tank. As we all know, the tumbler will not fall over no matter which direction the force is applied, and its core is because of its low center of gravity. Therefore, in order to ensure that it can maintain its center of gravity in huge waves and avoid capsizing, the warship will also
The center of gravity is designed toward the bottom, which is the legendary ballast water tank. The ballast water tank can not only lower the center of gravity of the ship, but also greatly increase the correction force of the warship when its attitude is deflected. Therefore, even if the warship is tilted to
The fact that it can still keep from capsizing at 45 degrees depends on the function of the ballast water tank.
Finally, there is the stabilizer fin. To deal with waves attacking from the front, a warship can use its V-shaped bow to cut through the waves, but for horizontal wave crests, it poses a huge safety hazard to the stability of the warship. Sometimes the ballast water tanks
The deflection strength is no longer enough to correct the overall attitude of the warship, so it is necessary to use stabilizer fins. The stabilizer fin is a bionic product inspired by the pelvic fins of fish. It is generally installed on the bilges on both sides of the ship (
The joint between the bottom and the side of the ship), when waves hit the stabilizer, can generate a deflection moment opposite to the direction of movement of the hull, thereby reducing the rolling of the hull.
Therefore, for 054a, a level 7 wave is really, as Wang Haiyang said, "not a big deal."
As time passed, the sound of Fatty Wei blowing water in the cabin gradually became quieter.
In the end, he actually stopped talking.
Li Zheng, who had been sitting by the bed reading, suddenly felt something was wrong. He looked at his watch and saw that it was already ten o'clock in the evening.
He turned to look towards Fatty Wei.
At this time, Fatty Wei was like an old monk in meditation, sitting by the bed without saying a word, looking a little weird.
"Fat man, are you seasick?"
Li Zheng asked.
Fatty Wei grinned, with a slightly bitter look on his face: "Where did that come from? Is it possible?!"
"Is it really okay?"
"It's okay! I remember back then..."
Before he finished speaking, Fatty Wei suddenly vomited. He quickly grabbed the plastic bag that had been prepared nearby, opened it, and spit into it twice more.
Wang Haiyang burst out laughing: "Fat man, we just arrived at Xisha! Didn't you often fish in this area before? Why are you seasick?!"
Fatty Wei wiped his mouth, but he was still very angry: "I'm not seasick. I ate too much at night. I can't chew the cud!?!"
